Whisk together coconut oil, cacao, sea salt and sweetener until smooth and creamy. Taste to adjust flavors to your preference.
Place mini muffin tins into an 8 x 8 dish or other tray for stability.
Spoon a teaspoon of “melted” chocolate into each mini muffin tin, then place in the freezer for a few minutes to set.
Remove cups from freezer and spoon a tiny dallop of nut butter into each tin, followed by a teeny dallop of coconut nectar. Because coconut nectar is so stretchy, I assist the process by pouring with my left hand very carefully, and “cutting” the stream of nectar off w/ a knife in my right hand. Feel free to add the pinch of fleur de sel (or sub celtic or himalayan salt) at this point, or wait til step 6 and sprinkle it on the tops.
Place cups back in freezer for 20 minutes. Remove cups from freezer and top with chocolate til covered. Sprinkle tops with a bit of Fleur de Sel (or celtic or himalayan salt) if you haven’t already done so in step 4. Pop back in freezer for a good hour til fully hardened
Store and eat directly from the freezer.
